To all whom tt'mcy concern:

Beit known that I, JOHN D. SULLIVAN, of Salt Lake City, in the county ofSalt Lake anchv State of Utah, 'have invented certain new and usefulImprovements in Fireproof Walls and Partitions; and I do hereby de*clare the following to be a full, clear, and eX- act descri tionfof theinvention, such as will enable otli appertains to make and use the same.

he primary object of this invention istov s construct the blocks orsections composing a ireproof wall or partition as to render shows acorner block Ior section.

unnecessary the use of laths, studding, or o'rounds of any kind; an'dwhich may be used lor either exterior or interior purposes. And

'a further object is to provide a iire roof wall or partition which willoccupy ut little s ace; which will re'quire but one coat of p aster;which will be sound-proof; which will form conduits for pipes and wires;and to which the trim or finish may be directly secured. l A

The invention will be hereinafter fully set particularlypointed 'out inthe claims.

In the accompanying drawings, Figure 1 is a side elevation, with partsin dotted lines. Fig. 2 is-a transverse sectional view on line 2-2',Fig. l. Figs. 3 and 4 are opposite edge views, with portions ofadjoining blocks lbroken away. Fig. 5 1s a longitudinal sectional viewon line 5 5, Fig'. Fig. .6 Fig. 7 is a vertical longitudinal sectionalView of a portion of a completed Wall or partition.

Referring to the drawings, l designates a block in its entirety. It isformed with spaced apart' sides 2, a central Vconnectin web 3 and-twoendI connecting webs 4, all being integral. The intervening hollowspaces 5 may be employed as conduits for pipes and wires, and beingdead-air spaces serve as sound deadeners. In each endof the block,between the `sides 2, is formed a roove 6, the

. faces of the webs 4 being slight y concaved.

The opposite ends of these grooves are slightly l'ared or b elled, as'at 7 and the opposite ends of the web 3 are formed with recasses 8.Theblock is preferably composed of fibrous gypsum hard .wallplaster`rcomposit-ion, and in each-side 21is a'fmetalli'c vre-inforcemerlt9,'preferabl wire-mesh.. 1

In budding up'f'aj wa l or partition; the series of blocks composingeach row are ar'- ranged end tof the contiguous grooves 6 ers skilled inthe Vart to which itv forming a space or chamber which is de- Signed tobe cned with a plastic binder, para.

erably fibrous plaster, the binder being poured in-at the top. In thisway the several Ablocks composing each row are secured togetheri'ii; Theblocks of the next or super,- posed row are arranged to break-joint withthe blocks ol the lower row, the webs 3 being thereby caused to coincidewithr the plaster filled spaces or chambers. The. recesses in the lowerends-of webs 3 are trowel-lled 'of'rny invention will be apparent. Theconnecting webs 3 and 4 formvsolid piers extendstudding or .groundsunnecessary," since the i trirn orf/finish may be nailed directly to theweb-formed piers. Not| only is the wall soundproof, but the spaces 5 maybe utilized as conduits. Each block may be made of' any desiredthickness and of any suitable" length .and height, and under ordinarycondi# er at topand l ing from ioor to ceiling, rendering the use`otions a wall thus formed occupies only about one-half the space of anlordlnarylath,l and plaster wall.' .I

I claim as Inyvinvention: 1. A rwallerpartition composed of superposedrows' of blocks, each block having g `spaced-apart sides and websconnecting sai sides at their centers and ends, vertical grooves beingformed in each end of the block and recesses in theupper and lower endsof the central webs, and plasticfbindin material in said grooves andrecesses, the en webs of the blocks of one row bein located in line withthe central webs-of the locks of the next adjacent'row, the spacesbetween said sides and the central and end webs forming conduits.

2. ,A wall `or partition composed 'of superposed rows of blocks, eachblock havin spaced-apart sides and webs'connecting sai `sides at theircenters and ends, vertical fg'ooves being formed in each end of the ockand recesses in the upper"'and lower ends of the' central Webs, saidgrooves lat,4

l 4. The herein-described block for walls or partitions composed ofreproof material and formed with spaced-apart sides, each i side havingmetallic reinforcing therein, such l block having Webs connecting saidsides at or their ends being belled, and plastic binding material inseid grooves, the belled ends thereof and said recesses, the end webs ofthe blocks of one row being located in line with the central webs of theblocks of the next adjacent row, the spaces between said sides and thecentral and end webs forming conduits.

3. The wall block herein described consisting of two spaced-a art sidesand webs orined therein. l formed integral with sai sides at the centersIn testimony whereof, I have signed this and ends thereof, long narrowconduits beingr I specification in the presence of two subscribforrnedbetween said sides and closed at thel ing witnesses. ends by said webs,"grooves being formed be i JOHN D.
